vidsrc in uvch264 fails

[Sneha Murganoor]

Hi,

Following pipeline fails. How to debug this? What is going wrong?

gst-launch-1.0 -v uvch264src device=/dev/video0 name=src auto-start=true
src.vidsrc ! queue ! video/x-h264 ! h264parse ! avdec_h264 ! xvimagesink
sync=false

But from vfsrc is working fine.

gst-launch-1.0 -v -e uvch264src device=/dev/video0 name=src
auto-start=true  src.vfsrc ! queue !
video/x-raw,format=\(string\)YUY2,width=320,height=240,framerate=10/1 !
textoverlay text="Capture from vfsrc 79879 " font-desc="Sans 24" !
xvimagesink sync=false

Thanks,
Sneha
